Hi,

I've successfully used attachments (using mime type "text/plain") to send
Strings as input parameters and as return values.  Now I'm trying to return a
byte array ( byte[ ] ) and am consistently failing because I'm not picking the
proper mime-type.  Here's what I've tried along with the resulting error
messages.

javax.activation.UnsupportedDataTypeException: no object DCH for MIME type
application/octet-stream

javax.activation.UnsupportedDataTypeException: no object DCH for MIME type
application/x-binary

javax.activation.UnsupportedDataTypeException: no object DCH for MIME type
application/pdf

I'm running IBM's WSAD with a WebSphere 4.0 test environment (which uses J2EE
1.2, and the mail and activation jars are within the j2ee.jar).

What mime type should I be using?  Thanks!

. . . Phil
